NETWORK COPOLYMER CROSSLINKED EMULSIONS AND DEMULSIFYING COMPOSTIONS COMPRISE THE SAME

The present invention is directed to a network composition the reaction product of: (i) at least one anionic polymerizable ethylenically unsaturated monomer (I) selected from the group consisting of [CH2 C(R3)C(O)OXa(C2H4O)b(C3H6O)c(C4H8O)d]pP(O)(OY)q(OZ)r where R3 H or alkyl of 1 to about 6 carbon atoms; X=alkyl, aryl, or alkaryl diradical connecting group of 0 to about 9 carbon atoms; a is 0 to about 100; b is 0 to about 100; c is 0 to about 100; d is 0 to about 100; q is 0 to about 2; r is 0 to about 2; p is 1 to about 3 subject to the limitation that p+q+r=3; and Y and Z is H, or metal ion; and CH2 C(R3)C(O)OXa′(C2H4O)b′(C3H6O)c′(C4H8O)d′-SO3-Y) where R3 H or alkyl of from 1 to about 6 carbon atoms; X=alkyl, aryl, or alkaryl diradical connecting group of 0 to about 9 carbon atoms; a′ is 0 to about 100; b′ is 0 to about 100; c′ is 0 to about 100; d′ is 0 to about 100; Y is H, or metal ion; and (ii) one or more additional monomers (II) selected from the group consisting of acrylic acid/acrylate, methacrylic acid/methacrylate, acrylamides, vinyl acetate and styrene, which are copolymerizable with (I); and (iii) a cross-linking agent (III), capable of copolymerizing with (I) and (II).
